qemu: make ptest rework

After qemu upgrades to 5.2.0 in commit [1], if also switches
to meson and the previous logic which introduces the testsuites
changes in [2] and results in below error when run ptest test:
 # ./run-ptest
 for f in ; do \
     nf=$(echo $f | sed 's/tests\//\.\//g'); \
     $nf; \
 done

So refactor the ptest part code to make it work again.
